How to Develop an App in Under 1 Hour and 200 Lines with Kotlin
summary
A live demo shows a real geolocation Android app built in under an hour and about 128–150 lines of Kotlin. It uses Kotlin features (data classes, extension functions, delegates, object singletons), Google Maps and LocationServices, a mocked route generator for repeated locations, simple filtering/sorting to pick the top three open venues, and background thread pools for network calls; the demo compiles and runs onstage.
